dc.description.abstractGroundwater is an essential part of the hydrological cycle serving as the primary source of water where public water supply is neither available nor adequate. This study evaluated the seasonal variability of water quality with respect to monthly rainfall depth in Ilorin metropolis, Nigeria. This was achieved by the determination of the month with minimum and maximum rainfall depth as well as determination of the concentration of Physico-chemical and bacteriological parameters of water sample in the study area. Twenty years historical data of monthly rainfall depth was obtained and analysed and a total of 32 water samples were collected from Shallow wells in the month with minimum and maximum rainfall depth from 8 different locations in year 2018 to determine their concentration. The Physico-chemical and bacteriological properties of water samples were analysed using Standard Methods. The potability of the water samples were assessed with respect to WHO standard. The study revealed that Turbidity, Fe2+, Dissolved Oxygen, Total Viable Count and Total Coliform Count concentration exceeded the Word Health Organization (WHO) standard in all the samples. Hence, the Shallow well water sources are polluted and the concentration of these pollutants increased in the month with minimum rainfall depth. The reduction in the pollutant concentration during the month with higher rainfall depth might be as a result of dilution through groundwater recharge from precipitation. The study also shows that the wells are not safe sources for drinking purposes and some form of treatment will be required before consumption.en_US
